Hunting with my Ar15/MSR

7/23/2015

8 Comments

 
     I love hunting with my AR15/MSR with a 16.5” barrel chambered in 5.56 NATO loaded with either 65gr sierras or my personal favorite 70gr Speers. I have taken lots of deer with those combinations and had never had any trouble recovering a shot deer.   I have not taken a few shots on some nice bucks because I thought they were just a bit out of range for the cartridges capabilities, at least as far as the self-imposed limits I placed on it.  I had also carried and used an Armalite .308 win and Armalite 300 RSAUM both being capable of taking deer at longer ranges but both very heavy to carry. I wanted a lighter gun that would be that would be flat shooting and still give me more energy on target at longer ranges if needed.

The 7mm Valkyrie/7mm VAR is perfect for this role, it’s exactly what I wanted, it’s a cartridge that fits in the in the AR15 platform (so I could keep it light weight and use more available components) that could shoot a heavier bullet but still be flat shooting. Where I deer hunt most of our hunting is in thick woods or swamps, located near Holcombe, Wisconsin it’s in the northern corner of Chippewa County in Northwest Wisconsin. We hunt tamarack and tag alder 


swamps surrounded by raspberry bushes so thick cottontails could not make it through without losing some fur. When we are not doing drives (yes, it’s legal in Wisconsin and part of our hunting tradition) we may sit in stands overlooking swamps or on the many irregular shaped farm fields and logging roads.

Looking out of Hoyts stand thick cover means you need to take precise shots through openings in the brush.

Looking down the side of my 40, that’s 440 yards of possible shooting, the 7VAR can drop a deer anywhere along that tree line.
  Most of the time I  can’t even see a deer past 20- 50 yards but we do have some stands on swamps about 200 – 500 yards across and on some  long straight logging roads. I prefer short light semiauto rifles/carbines for our type of hunting, it’s not uncommon to see several deer at a time and being able to have quick follow up shots on target are a real asset. Having a flat shooting semi auto allows us to make precision shots through the brush with fast follow up. Despite popular myths even a small twig will throw of the trajectory of any bullets.   Slow moving round bullets will actually deflect more than a fast moving long bullet.

  The 7mm VAR fit my requirements perfectly, with my 16.5’’ barrel and a 2x7x33 or an Eotech my gun weighs 7 pounds. It is  capable of pushing 120gr Nosler ballistic tips 2800 fps, 130gr Speer 2700 fps, 139gr Hornady SST at 2560 fps, 160 federal fusion at 2466 fps, 168 Nosler custom competition at 2425fps.   This is more than adequate for deer and Black Bear out to 400 yards or more with most loads.  This Carbine was built for my son Hoyt to shoot out of a stand.

  The 7mm VAR is for reloaders only and does not require anything too special to load if you buy brass converted already. Hodgdons Leverevolution has been giving the best velocities, CFE223 being second, with the 130 and up class bullets, H335 and 8208BRX have been great with the 120s and up. I also have a 20’’ barrel and the velocities have been consistently about 28 fps per inch faster, longer barrels will get even more velocity. Many loads have already shown SUB MOA capability with a few less than .5 MOA.

  The brass I use is made from 6.5x47 Lapua. It has a small primer and will give the best case life. It can be made from surplus .308/7.62 NATO or other 308 or 6.5 Creedmoor brass but it is much more work with lots of cases needing to be scrapped due to malformation when sizing. It’s just not worth all the work compared to the lapua brass.  

  Load data is being worked up for many different bullet, primer and powder combinations. We will have a complete load book eventually with a load to cover just about any practical use with real world data. All of guns are shot off the bench, they are not a test barrel locked in a vice. The data is also being shot in barrels 16.5” to 24” in the Ar15 platform.   We have shot Speer 110gr TNT up to Nosler Custom Competition 168gr which are both  super accurate even out of the 16.5” they are near one hole capable at 100yds. This could easily be a do it all hunting rifle for many people, from taking predators and varmints up to bear and elk. It will defiantly be the coolest gun in Deer camp.

  Others using the cartridge with heavier bullets will  load them longer (2.345’’)so they may (window) or cut out the front of the magazine,  ( there is a good video that shows how to do this) I prefer to only shoot bullets up to 145gr for deer  and load all of mine to magazine length or slightly shorter. The PRI 6.8 magazines work best, they are waffled and are much stiffer, just holding one in your hand will let you know it’s built to be tough. Cheaper mags can be used but they will not have the capacity due to the thin weaker construction letting the sidewalls bulge out. So far my favorite bullet has been the Speer 130gr with CFE 223 it has been super accurate with several groups less than 0.5in. The recoil is not too bad either, the 16.5’’ was built for my son Hoyt who at 9 years and about 70# says it’s about like his .410 shotgun with 3” heavy loads.

  The 7VAR has exceeded my expectations in every way. Having standard factory load 7mm-08 performance in a semi auto gun that’s easy to customize and easy to carry are a big plus for me. Who can deny the power and long range capabilities of the 7mm-08.

  The 16.5” upper receiver and carrier is standard stuff from BCM, the hand guard is a Midwest Industries 9” carbine lightweight free float handguard. It will wear an Eotech 552 for Hunting.  Loaded with 130gr Speer BTSP or Sierra 120gr SP either will be deadly on deer.

  The 20” upper is a billet from Midwest Industries with a BCM carrier. The hand guard is a Midwest Industries Gen2 SS free float. It is by far my favorite hand guard. It will wear a Leopold VX1 2-7x33 scope.

  The lower receiver pictured is a Midwest Industries billet with a Geissele SSA-E trigger, it’s nice and I have no complaints other than the cost.

  Ace skeleton stock is by far my favorite light weight fixed stock. The foam is nice on the face when it’s cold.

  I use Simmons 6-24x50 whitetail classic scopes for load development. The cross hairs are a little thick but  I use  the 1” orange target spots with the little black diamond and can line it up perfect every time and the glass is good enough even on foggy days. For $100 you can’t beat it. 

  The Nikon 223 mounts work well and were a deal, $59 at Cabela’s on sale, the 2 piece Nikon are also working out well with no issues.

   Both are Cerekoted Magpul OD green, and have the large BCM gunfighter charging handle, they are nice when you have optics or are trying to use it with thick gloves. Midwest Industries low pro gas blocks.

  We look forward to hunting this fall with the 7mm Valkyrie and I’m sure there will be many others using it in the near future also.

First range trip with my 7mm Valkyrie

So my first trip with the 7mm VAR was pretty productive. My main goal was to collect data for future loading and get a feel for the cartridge. I provided the targets for the hell of it, since some of the ladder tests shot better than my 5.56 AR. So I am really liking the X-Caliber barrel.

Initial impressions on the powders are as follows. LeveReloution : Still need to test more, but so far I like it. 8208 XBR : Its reputation for accuracy was seen pretty early on with the. Even with the ladder test 140 TTSX wasn't terrible. CFE223: This is a powder that should be avoided on barrels longer than 20", although if you have a mild charge on a 20" barrel you could still produce the double pressure spike. Please reference String 11 and notice shot 10 has a double pressure spike that almost mirror each other.

I have attached a chart of Optimal Barrel Times for different barrel lengths. (If you would like the Excel file, let me know.) It will provide reference for the exit time for images Pressure Spike 1 & 2. So in theory you should be ok with a shorter barrel, something I would want to confirm.

Rem 7 1/2(Lot#986) seems to be the goto primer, as CCI 450 & Wolf KVM-223M would produce double pressure spikes. Even though the Muzzle Velocity of CCI 450(Lot#K16U11) & Wolf KVB-223M (Lot#1-10) were slightly better than Rem 7 1/2. Reference String 1-3, these were my primer comparisons. String 4 A & B were actually shot first, to sight in the rifle & initial function check / troubleshooting.

With the rifle I did have some issues, FTE & FTF. The Failure to Extract was from the bolt cycling too fast. I was using a standard Carbine buffer. Forgot to bring my H3 buffer which I think would have solved the issue. Lost 3 brass to cycling issues, necks were too badly damaged for me to salvage. But in most cases the brass was turned around in side the ejection port area, and as my firing went on, the brass would just sit in the ejection port area. Glad I brought my Bob Led Sled, which allowed me to finish the day out at a slower pace. The Failure to Fire could have been 1 of 2 possiblities, the Voodoo Tactical lifeproof coated firing pin and/or the Wolf primers. I suspect its the firing pin since I was able to get the round to go off once I removed the BCG and cycled the bolt open to close and moved the firing pin. Re-inserted and would fire round. Had this happen with I think 1 CCI primer, but I'm not sure since I was in a rush to shoot off the ammo.

Overall, I am very impressed with the 7mm VAR. I knew that there would be a couple kinks to work out, especially the buffer/gas system relationship. But the round paired with the barrel proved to be a wonderful relationship. I have not had the best experience with Barnes bullets with my other rifle, but glad to see that this will not be the case in this rifle.
